shrimp Posted March 17, 2010 Author Report Share Posted March 17, 2010 Yea, what the other guys are saying. I wouldn't recommend 20cc domes on a stock motor at sea level on pump gas. Detonation will lift the domes and blow the oring. When you put it back together, run larger domes or higher octane (or both). -David hey david i talked to you about a year ago. its the same problem its a 4mill cheetah cub. no porting Quote Link to comment Share on other sites More sharing options...
firebanshee Posted March 17, 2010 Report Share Posted March 17, 2010 93 pump gas You are going to have to keep your compression down around 155-160, probably have to have a 23 or 24cc dome. I am sure Noss can hook you up. Quote Link to comment Share on other sites More sharing options...
